Abstract:

Objective

To explore weight change among patients following bariatric and metabolic surgery and to analyze the influencing factors.

Methods

We used convenience sampling to recruit 199 patients underwent bariatric and metabolic surgery from a tertiary hospital between January and February in 2020. We applied general information questionnaire, general self-efficacy scale, general health questionnaire and social support rating scale to investigate. We used t-test, analysis of variance and multivariate linear regression to analyze the influencing factors.

Results

The difference of body mass index (BMI) between patients undergoing weight loss surgery before and after surgery was (10.97±7.10) kg/m2, and the effect of weight loss after surgery was good. Multiple linear regression analysis showed that social support, self-efficacy, surgery method and living style entered the regression equation (P<0.05). A total of 28.8% of the total variation in postoperative body mass weight loss was explained.

Conclusions

The weight loss of patients after bariatric surgery is obvious, the level of social support, self-efficacy, operation mode and living mode are the main factors affecting the effect of weight loss.
